A plasma physics paper written by Distinguished Professor Dr. Gary Zank, the chair of the UAH Department of Space Science, has been selected as one of 12 Classic JPP Papers published by the Journal of Plasma Physics. "I was quite delighted to receive the notification email, since this represents recognition of the long-term lasting impact of my work – at least one aspect of it – on my scientific community," says Dr. Zank. Dr. Zank's paper, "The equations of reduced magnetohydrodynamics" (Journal of Plasma Physics; JPP 48, 85; 1992), was selected by the journal's editorial board from all papers published in the journal with more than 100 citations. The paper presented a mathematical derivation of a plasma physics model that describes how plasmas behave in the presence of a strong magnetic field.
